Week of February 22, 2016

This Week in AP Physics
We will begin exploring our electrostatics unit in earnest. Our first focus will be the nature of charge, methods of charging, and electric force. We’ll punctuate this topic with the Charging by Induction lab, which is a fun one! (Of course, they’re all fun, right?) Expect a doozy of a problem set, and then things start to get a little more relaxed as we explore electric field with notes, problems, and a really cool experiment (and I mean that – It’s a particularly cool one that people tend to love.) This will likely spill into next week, when we will finish the unit by exploring electric potential energy and electric potential. Finally, your lab report for your Behavior of Gases lab is due on Friday. (Remember that the hardcopy of your lab will be due at the start of class on the due date; an upload  is due to TurnItIn.com by 3:00 of that day. Remember to write using Google Drive and share your document with me at alhsgb@gmail.com…Note that I do not use that address for email correspondence. Be sure to use the lab document as well as the lab report writing guide and lab report rubricas you write.)

This Week in Physics
We will start the week by clarifying some final points about circular motion and doing the experiment we were unable to get to last week due to scheduling. (You will have a lab report to write for this experiment, and the due date will be announced in next week’s blog.) Expect a quiz over the topic of circular motion by midweek. Also, when announced, please take notes on Podcast 5 – Gravity and Podcast 6 – Center of Mass, Gravity, and Planetary Orbits. We will cover these topics and do assignment 2. Expect a unit test next week.

Cool Science of the Week
Want to know if an earthquake is coming? There’s now an app for that! MyShake gives you a readout of current seismic conditions and can provide you with a few seconds of warning, since it can detect seismic changes before you do. Interesting! (Currently only available for Android, with an Apple version in development. It is a free app. Disclaimer: I don’t own any part of the app (darn it!))
